  What are the differences between DDP and FOB. which method is more convenient and less risky for us buyers?

  Hello! Regarding the choice between DDP and FOB, I will summarize it simply and clearly to help you make a decision:
  If you choose DDP, you only pay a fixed total price. You don't need to worry about any processes or risks; you just wait for the goods to arrive at your door, check, and sign for them. The budget is fixed, with no hidden costs. You can maximize savings, ensure a fixed total cost, and transfer complexity and risk to the supplier's customer.
  If you choose FOB, theoretically, it gives you more control, the potential to find lower shipping costs, and you have a strong and reliable local team or long-term freight forwarder in the destination country that can efficiently handle customs clearance and logistics. The primary goal is to pursue the theoretically lowest total procurement cost. However, you need to bear the risks of sea freight delays and increased costs at the destination port.
  It all depends on which aspect you value more. If your primary goal is "peace of mind, certainty, and no surprises," then DDP is a better and more reliable choice.

  What are the different types of galvanizing?

  1. Hot-dip galvanizing: This involves immersing metal in molten zinc to form a coating. It offers excellent corrosion resistance and mechanical strength and is widely used in construction, bridges, and other fields.
  Features: Thick coating (typically 50-150 micrometers), long service life, suitable for outdoor environments.
  Process classification: There are two types: with spots (zinc crystals are visible) and without spots (uniform surface), which does not affect performance.
  2. Cold galvanizing (electro-galvanizing): A zinc layer is deposited on the metal surface through electrolysis. The thickness is relatively thin (5-30 micrometers), which is suitable for occasions with high aesthetic requirements.
  Advantages: Uniform coating, bright appearance, and can undergo color passivation treatment.
  Limitations: Its corrosion resistance is weaker than that of hot-dip galvanizing, and it is mostly used indoors or in mildly corrosive environments.
